Start and end frame control in Flux 3 Max
Start from words and Flux 3 Max builds the whole shot. Start from a picture and it animates forward from your start frame. Add an end frame too and it plans the motion between them, so the clip lands exactly where your storyboard says it should: a product reveal that ends on the packshot, a trailer beat that cuts between two key images.
Flux 3 Max output: 20-second 1080p video with native audio
Set the length to the second, anywhere from 5 to 20, and render at 720p for drafts or 1080p for the final cut, in eight framings: auto, 21:9, 2:1, 16:9, 4:3, 1:1, 3:4 and 9:16. Audio is on by default and can be switched off. A reasoning level setting (low or high) trades speed for care, and a fixed seed reproduces a take you like.
